Re: [PSES] Antenna tilting or bore sighting for radiated emissions

Hi Larry, Thanks a lot for your insightful comments. Yes I'm familiar with the setup and with the antenna 3dB beamwidth. My question aims to help me estimate how much is it worth the investment in a mast with tilting or boresighting capability for our 3m semi-anechoic chamber. Most of the tests
